Blue Planet
Cyan Blue Planet is a software-defined network (SDN) system built specifically for service
provider networks. Blue Planet lets service providers of all types virtualize their networks, flatten
legacy cost structures, make more efficient use of network assets, and accelerate service
delivery.
Blue Planet is composed of three distinct elements: an open SDN platform, SDN apps, and
element adapter apps facilitating control over a wide range of third-party network devices.
BOSS
Broadband Operating System Supervisor — The BOSS card provides common shelf control
functionality to Cyan Z77 nodes.
BTM
BOSS Termination Module — The BTM houses the Cyan Z77 physical connectors for
management and timing interfaces.
BPDU Bridge Protocol Data Unit
CAC
Connection Admission Control — CAC is
used for Traffic Engineering configuration and helps to
control congestion in a connection-oriented network such as Carrier Ethernet. CAC is used
during the set up of a connection to determine if the Quality of Service (QoS) is valid for the
connection request and to verify that there are sufficient resources available to allow a new
connection. The QoS of the new connection cannot affect the QoS of existing connections.
CBS
Committed Burst Size — The Committed Burst Size is a bandwidth profile parameter. CBS limits
the maximum number of bytes available for a burst of service frames sent at the UNI speed to
remain CIR conformant.
CCM
Continuity Check Messages — CFM Continuity Check Messages are multicast heartbeat
messages exchanged periodically among MEPs
. CCMs allow MEPs to discover other MEPs in
a domain and allow MIPs to discover MEPs.
CDF Client Data Frame
CE
• Customer Equipment
• Carrier Ethernet
• Customer Edge
• Circuit Emulation
CEM Common Equipment Module
CFI Canonical Format Indicator
CFM
Connectivity Fault Management — Connectivity Fault Management is an IEEE 802.1ag
end-to-end per-service-
instance Ethernet OAM protocol. CFM provides connectivity monitoring,
fault verification, and isolation for carrier networks. CFM uses standard Ethernet frames.
CIR
Committed Information Rate — The Committed Information Rate is a bandwidth profile
parameter. CIR defines the average bits per second of service frames up to which the network
delivers service frames and meets the performance objectives defined by the Class of Service
(CoS) service attribute.
CIST
Common and Internal Spanning Tree identifies the regions in a network and administers the
CIST root bridge for the network, the root bridge for each region, and the root bridge for each
spanning-tree instance in each region.
CoS Class of Service
Service frames delivery and performance levels agreed to by the service provider.
CPE Customer Premises Equipment
CSF Client Signal Fail
CSV Comma-Separated Values
C-VID Customer VLAN Identifier
C-VLAN Customer VLAN
CWDM Coarse Wave Division Multiplexing
CWDM uses the center wavelengths from 1271nm to 1611nm with a channel spacing of 20 nm.
